Severus glanced up as he noticed someone approaching his table in the Muggle library. He was dressed in a long-sleeved black band t-shirt and ripped jeans, and his hair tied back.

"If you don't have a reason to bother me, go away," he said pointedly. Without waiting for a response, he turned his attention back to his books and notes, dismissing the interruption.
